Demodex Blepharitis

Demodex is an 8-legged ectoparasite, meaning it lives on the surface of a host. It can live in hair follicles and sebaceous (oil) glands.

Blepharitis is a condition of eyelid inflammation that causes inflammation, as well as disruption in tear production.

Pictured: One of the primary observations made by an eye-care professional is col-md-6larettes around the eyelashes, prompting further investigation of demodex.

Demodex infestation of the eyelids causes blepharitis. They have a life span of 2-3 weeks and lay about 15-20 eggs each in the eyelash hair follicle near the sebaceous glands. They consume epithelial cell cytoplasm by piercing through the cell membrane.

Treatment:

Once demodex are discovered via a slit lamp examination, a full debridement of lashes and eyebrows is done using a cotton tip applicator soaked in 100% tea tree oil solution. This irritates the mites and stimulates them to leave the eyelash follicle.

This process is repeated after 10 minutes.

The eyelids are treated with antibiotics and steroids. These prevent mites from moving and possibly suffocates them.

The steroid treatment specifically helps calm the inflammation that results from the irritation of the procedure. It also suppresses possible inflammatory cascade associated with the decaying mites.

Important Instructions:

ÞReturn for a two week repeat treatment

ÞUse eyelid scrubs every night to clean the eyelashes

ÞRemove all sheets and pillowcases and wash, drying on a high setting.
